The process value is visualized on 4 red displays, while the output status is indicated by 2 LED displays. The instrument is equipped with a 3 LED programmable shift indexes and can have up to 2 outputs: relay type or can drive solid state relays type (SSR). Depending on the model required the input accept: C: Thermocouples temperature probes (J,K,S and IRS Infrared sensors), mv signals (0..50/60 mv, mv), Thermoresistances PT100. E : Thermocouples temperature probes (J,K,S and IRS Infrared sensors), mv signals (0..50/60 mv, mv), Thermistors PTC and NTC. I : normalized analogue signals 0/4..20 ma V : normalized analogue signals 0..1 V, 0/1..5 V, 0/2..10 V FRONT PANEL DESCRIPTION AT CNT OUT1 TLK 96 SET OUT2 1 - Key P : This is used to access the programming parameters and to confirm selection. 2 - Key DOWN : This is used to decrease the values to be set and to select the parameters. If the key is held down, the user returns to the previous programming level until he exits the programming mode. 3 - Key UP : This is used to increase the values to be set and to select the parameters. If the key is held down, the user returns to the previous programming level until he exits the programming mode. Outside the programming mode it permits visualisation of the output control power. 4 - Key U : It can used to Activate Auto-tuning and Self-tuning functions and modify the visibility of the parameters in ConF menu (see par. 2.3). 5 - Led OUT1 : indicates the state of output OUT1 6 - Led OUT2 : indicates the state of output OUT2 7 - Led SET : It indicates access to the programming mode and parameter programming level. 8 - Led AT/ST : indicates that the Self-tuning function is activated (light on) or that Auto-tuning (flashing ) is in progress. 9 - Led Shift index: indicates that the process value is lower than [-AdE] Led = Shift index: indicates that the process value is within the range [+AdE... -AdE] TLK 96 S - OPERATING INSTRUCTIONS - Vr ISTR PAG. 1

2 11 - Led + Shift index: indicates that the process value is higher than [+AdE]. 2 - PROGRAMMING FAST PROGRAMMING OF THE SET POINT This procedure permits rapid programming of the Set Point () and Set Point (SP2) Push key P, then release it and the display will visualise SP 1 alternatively to the programmed value. To modify the value, press UP key to increase it or the DOWN key to decrease it. These keys change the value one digit at a but if they are pressed for more than one second, the value increases or decreases rapidly and, after two seconds in the same condition, the changing speed increases in order to allow the desired value to be reached rapidly. Push key P, then release it and the display will visualise SP 2 alternatively to the programmed value. To modify the value, press UP key to increase it or the DOWN key to decrease it. These keys change the value one digit at a but if they are pressed for more than one second, the value increases or decreases rapidly and, after two seconds in the same condition, the changing speed increases in order to allow the desired value to be reached rapidly. To exit the fast Set programming it is necessary to push key P, after the visualisation of the last Set Point, or alternatively, if no key is pressed for approx. 15 seconds, the display will return to normal functioning automatically. Set Point ( and SP2) can be programmed with a value that is between the value programmed on par. SPLL and the one programmed on par. SPHL PARAMETERS PROGRAMMING By pushing key "P" and holding it down for approx. 2 sec. it is possible to enter into the main selection menu. Using the UP and DOWN keys, it is possible to select the desired parameter and, if the key P is pressed, the display will alternatively show the parameter s code and its programming value, which can be modified by using the UP or DOWN keys. Once the desired value has been programmed, push key P once more: the new value will be memorised and the display will show only the code of the selected parameter. By using the UP or DOWN keys, it is then possible to select a new parameter (if present) and modify it as described above. To exit the programming mode, no key should be pressed for approx. 20 seconds, or keep the UP or DOWN pressed until exit from the programming mode is obtained. 3 - INFORMATION ON INSTALLATION AND USE PERMITTED USE The instrument has been projected and manufactured as a measuring and control device to be used according to EN for the altitudes operation until 2000 ms. The use of the instrument for applications not expressly permitted by the above mentioned rule must adopt all the necessary protective measures. The instrument CANNOT be used in dangerous environments (flammable or explosive) without adequate protection. The installer must ensure that EMC rules are respected, also after the instrument installation, if necessary using proper filters. Whenever a failure or a malfunction of the device may cause dangerous situations for persons, thing or animals, please remember that the plant has to be equipped with additional devices which will guarantee safety. 3.2 MECHANICAL MOUNTING The instrument, in DIN case 96 x 96 mm, is designed for flush-in panel mounting. Make a hole 90 x 90 mm and insert the instrument, fixing it with the provided special brackets. We recommend that the gasket is mounted in order to obtain the front protection degree as declared. Avoid placing the instrument in environments with very high humidity levels or dirt that may create condensation or introduction of conductive substances into the instrument. Ensure adequate ventilation to the instrument and avoid installation in containers that house devices which may overheat or which may cause the instrument to function at a higher temperature than the one permitted and declared. Connect the instrument as far away as possible from sources of electromagnetic disturbances such as motors, power relays, relays, solenoid valves, etc ELECTRICAL CONNECTION Carry out the electrical wiring by connecting only one wire to each terminal, according to the following diagram, checking that the power supply is the same as that indicated on the instrument and that the load current absorption is no higher than the maximum electricity current permitted. As the instrument is built-in equipment with permanent connection inside housing, it is not equipped with either switches or internal devices to protect against overload of current: the installation will include an overload protection and a two-phase circuit-breaker, placed as near as possible to the instrument, and located in a position that can easily be reached by the user and marked as instrument disconnecting device which interrupts the power supply to the equipment. It is also recommended that the supply of all the electrical circuits connected to the instrument must be protect properly, using devices (ex. fuses) proportionate to the circulating currents. It is strongly recommended that cables with proper insulation, according to the working voltages and temperatures, be used. Furthermore, the input cable of the probe has to be kept separate from line voltage wiring. If the input cable of the probe is screened, it has to be connected to the ground with only one side. We recommend that a check should be made that the parameters are those desired and that the application functions correctly before connecting the outputs to the actuators so as to avoid malfunctioning that may cause irregularities in the plant that could cause damage to people, things or animals. and its legal representatives do not assume any responsibility for any damage to people, things or animals deriving from TLK 96 S - OPERATING INSTRUCTIONS - Vr ISTR PAG. 2

Depending on the model required the input accept: C: Thermocouples temperature probes (J,K,S and IRS Infrared sensors), mv signals (0..50/60 mv, mv), Thermoresistances PT100. E : Thermocouples temperature probes (J,K,S and IRS Infrared sensors), mv signals (0..50/60 mv, mv), Thermistors PTC and NTC. I : normalized analogue signals 0/4..20 ma V : normalized analogue signals 0..1 V, 0/1..5 V, 0/2..10 V Depending on the model, using par. SEnS, it s possible to select the type of input probe, which can be : - for thermocouples J (J), K (CrAL), S (S) or for infrared sensors serie IRTC1 with linearization J (Ir.J) or K (Ir.CA) - for thermoresistances Pt100 IEC (Pt1) or thermistors PTC KTY (Ptc) or NTC 103AT-2 (ntc) - for normalised signals in current ma (0.20) or ma (4.20) - for normalised signals in tension 0..1 V (0.1), 0..5 V (0.5), 1..5 V (1.5), V (0.10) or V (2.10). - for normalised signals in tension mv (0.50), mv (0.60), mv (12.60). We recommend to switch on and the instrument when these parameters are modified, in order to obtain a correct measuring. For the instruments with input for temperature probes (tc, rtd) it s possible to select, through par. Unit, the unit of measurement ( C, F) and, through par. dp (Pt100, PTC and NTC only) the desired resolution (0=1 ; 1=0,1 ). Instead, with regards to the instruments with normalised analogue input signals, it is first necessary to program the desired resolution on par. dp (0=1; 1=0,1; 2=0,01; 3=0,001) and then, on par. "SSC", the value that the instrument must visualise at the beginning of the scale (0/4 ma, 0/12 mv, 0/1 V o 0/2 V) and, on par. "FSC", the value that the instrument must visualise at the end of the scale (20 ma, 50 mv, 60 mv, 5 V or 10 V). The instrument allows for measuring calibration, which may be used to recalibrate the instrument according to application needs, by using par. OFSt and rot. Programming par. rot =1,000, in par. OFSt it is possible to set a positive or negative set that is simply added to the value read by the probe before visualisation, which remains constant for all the measurements. If instead, it is desired that the set set should not be constant for all the measurements, it is possible to operate the calibration on any two points. In this case, in order to decide which values to program on par. OFSt and rot, the following formulae must be applied : rot = (D2-D1) / (M2-M1) OFSt = D2 - ( rot x M2) where: M1 =measured value 1 D1 = visualisation value when the instrument measures M1 M2 =measured value 2 D2 = visualisation value when the instrument measures M2 It then follows that the instrument will visualise : DV = MV x rot + OFSt where: DV = visualised value MV= measured value Example 1: It is desired that the instrument visualises the value effectively measured at 20 but that, at 200, it visualises a value lower than 10 (190 ). Therefore : M1=20 ; D1=20 ; M2=200 ; D2=190 rot = (190-20) / (200-20) = 0,944 OFSt = (0,944 x 200) = 1,2 Example 2: It is desired that the instrument visualises 10 whilst the value actually measured is 0, but, at 500 it visualises a 50 higher value (550 ). Therefore : M1=0 ; D1=10 ; M2=500 ; D2=550 rot = (550-10) / (500-0) = 1,08 OFSt = (1,08 x 500) = 10 By using par. FiL it is possible to program constant of the software filter for the input value measured, in order to reduce noise sensitivity (increasing the of reading). In case of measurement error, the instrument supplies the power as programmed on par. OPE. This power will be calculated according to cycle programmed for the PID controller, while for the ON/ controllers the cycle is automatically considered to be equal to 20 sec. (e.g. In the event of probe error with ON/ control and OPE =50, the control output will be activated for 10 sec., then it will be deactivated for 10 sec. and so on until the measurement error remains.). In the group ] PAn the par. AdE is present that defines the 3 led shift index functioning. The lighting up of the green led = indicates that the process value is within the range [+AdE... -AdE], the lighting up of the led indicates that the process value is lower than [-AdE] and the lighting up of the led + indicates that the process value is higher than [+AdE] OUTPUTS CONFIGURATION The instrument s outputs can be programmed by entering the group of parameters ] Out, where the relative parameters O1F and O2F (depending on the number of outputs available on the instrument) are located. The outputs can be set for the following functions : - Main control output (1.rEG) - Secondary control output (2.rEG) - Alarm output normally open (ALno) - Alarm output normally closed (ALnc) - Alarm output normally closed with led reverse indication (ALni) - Output deactivated () The coupling outputs number outputs number alarms can be made in the group referring to the alarm to the alarm ( ] AL1 ) ON/ CONTROL (.1rEG) All the parameters referring to the ON/ control are contained in the group ] reg. This type of control can be obtained by programming par."cont" = On.FS or = On.FA and works on the output programmed as 1.rEG, TLK 96 S - OPERATING INSTRUCTIONS - Vr ISTR PAG. 3

4 depending on the measure, on the Set Point, on the functioning mode "Func and on the hysteresis "HSEt". The instrument carries out an ON/ control with symmetric hysteresis if Cont" = On.FS or with asymmetrical hysteresis if Cont = On.FA. The control works in the following way : in the case of reverse action, or heating ( FunC =HEAt), it deactivates the output, when the process value reaches [ + HSEt] in case of symmetrical hysteresis, or [] in case of asymmetrical hysteresis and is then activated again when the process value goes below value [ - HSEt]. Vice versa, in case of direct action or cooling ("Func =CooL), it deactivates the output, when the process value reaches [ - HSEt] in case of symmetrical hysteresis, or [] in case of asymmetrical hysteresis and is activated again when the process value goes above value [ + HSEt]. SP OUT ON HEAt - On.FA HSE SP OUT HSE ON ON ON ON ON CooL - On.FA This function allows a control by on the output 2.rEG activation, independently by the temperature control request. The protection is a delayed after deactivation type. This protection permits to avoid the output activation for a programmable on par. CPdt (expressed in sec.); the output activation will occurs only after the elapsing of CPdt. The programmed on parameter CPdt is counted starting from the last output deactivation. Obviously, whether during the delay caused by the compressor protection function, the regulator request should stop, the output activation foreseen after CPdt would be erased. The function is not active programming CPdt =. The led relative to 2.rEG output blinks during the phases of output activation delay, caused by Compressor Protection function SINGLE ACTION PID CONTROL (1.rEG) All the parameters referring to PID control are contained in the group ] reg. The Single Action PID control can be obtained by programming par."cont" = Pid and works on the output 1.rEG depending on the Set Point, on the functioning mode "Func and on the instrument s PID algorithm NEUTRAL ZONE ON/ CONTROL (1.rEG - 2.rEG) All the parameters referring to Neutral Zone ON/ control are contained in the group ] reg. This type of control can be obtained when 2 outputs are programmed respectively as 1.rEG and 2.rEG and the par. Cont = nr. The Neutral Zone control is used to control plants in which there is an element which causes a positive increase (ex. Heater, humidifier, etc.) and an element which causes a negative increase (ex. Cooler, de-humidifier, etc). The control functions works on the programmed outputs depending on the measurement, on the Set Point and on the hysteresis "HSEt". The control works in the following way : it deactivates the outputs when the process value reaches the Set Point and it activates the output 1.rEG when the process value goes below value [ - HSEt], or it activates the output 2.rEG when the process value goes above [ + HSEt]. Consequently, the element causing a positive increase has to be connected to the output programmed as 1.rEG while the element causing a negative increase has to be connected to the output programmed as 2.rEG. HSEt HSEt OUT 1.rEG (HEat) In order to obtain good stability of the process variable, in the event of fast processes, the cycle has to have a low value with a very frequent intervention of the control output. In this case use of a solid state relay (SSR) is recommended for driving the actuator. The Single Action PID control algorithm foresees the setting of the following parameters : "Pb" - Proportional Band "" - Cycle of the output 1.rEG "Int" - Integral Time "rs" - Manual Reset (if Int =0 only) "der" - Derivative Time FuOC - Fuzzy Overshoot Control This last parameter allows the variable overshoots at the start up of the process or at the changing of the Set Point to be avoided. Please remember that a low value on this parameter reduces the overshoot while a high value increase it OUT 1.rEG (heating) OUT 2.rEG (cooling) If 2.rEG output is used to control compressor is possible to use the Compressor Protection function that has the meaning to avoid compressor short cycles. 1: Value FuOC OK 2: Value FuOC too high 3: Value FuOC too low AUTOTUNING FUNCTIONS All the parameters referring to the AUTO-TUNING and SELF- TUNING functions are contained in the group ] reg. TLK 96 S - OPERATING INSTRUCTIONS - Vr ISTR PAG. 4

5 The AUTO-TUNING and SELF-TUNING functions permit the automatic tuning of the PID controller. The AUTO-TUNING function permits the calculation of thepid parameters by means of a FAST type tuning cycle and, at the end of this operation, the parameters are stored into the instrument s memory and remain constant during control. The SELF-TUNING function (rule based "TUNE-IN") instead allows control monitoring and the continuous calculation of the parameters during control. Both functions automatically calculate the following parameters : "Pb" - Proportional Band "" - Cycle of the output 1.rEG "Int" - Integral Time "der" - Derivative Time FuOC - Fuzzy Overshoot Control To activate the AUTO-TUNING function proceed as follows : 1) Program and activate the desired Set Point. 2) Program par. "Cont" =Pid. 3) Program par. "Func" according to the process to be controlled through output 1.rEG. 4) Program an output as 2.rEG if the instrument controls a plant with double action 5) Program par. "Auto" as: - "1 if auto-tuning is desired automatically, each the instrument is switched on, on the condition that the process value is lower (with Func =HEAt) than [SP- SP/2 ] or higher (with Func =CooL) than [SP+ SP/2 ]. - "2" if auto-tuning is desired automatically, the next the instrument is switched on, on the condition that the process value is lower (with Func =HEAt) than [SP- SP/2 ] or higher (with Func =CooL) than [SP+ SP/2 ], and once the tuning is finished, the par. Auto is automatically swapped to the state - "3" - if manual auto-tuning is desired, by key U. The Autotuning will start at the condition that the process value is lower (with Func =HEAt) than [SP- SP/5 ] or higher (with Func =CooL) than [SP+ SP/5 ]. - "4" - if it s desired to activate the autotuning automatically to every change of Set Point. The Autotuning will start at the condition that the process value is lower (with Func =HEAt) than [SP- SP/5 ] or higher (with Func =CooL) than [SP+ SP/5 ]. 6) Exit from the parameter programming. 7) Connect the instrument to the controlled plant. 8) Activate the Auto-tuning by key U if Auto = 3 or switch and then on the instrument if Auto = 1 or 2. At this point the Auto-tuning function is activated and is indicated by the flashing led AT/ST. The regulator carries out several operations on the connected plant in order to calculate the most suitable PID parameters. If, at the Auto-tuning start, the condition for the lower or higher process value is not found the display will show ErAt and the instrument will be swapped to normal control conditions according to the previously programmed parameters. To make the error ErAt disappear, press key P. The Auto-tuning cycle duration has been limited to 12 hours maximum. If Auto-tuning is not completed within 12 hours, the instrument will show "noat" on the display. In case of probe error, the instrument automatically stops the cycle in progress. The values calculated by Auto-tuning are automatically stored in the instrument s memory at the end of the correct PID parameters tuning. If the instrument is switched during Auto-tuning function activated, these functions will remain activated the next it is switched on REACHING OF THE SET POINT AT CONTROLLED SPEED All the parameters referring to the ramps functioning are contained in the group ] reg. It is possible to reach the set point in a predetermined (in any case longer than the the plant would naturally need). This could be useful in those processes (heating or chemical treatments, etc.) where the set point has to be reached gradually, in a predetermined. The function is determined by the following parameter : "SLor" - Gradient of ramp expressed in unit/minute [Unit] SLor change Value SLor [min.] Example with start from values lower than SP 1 and with decreasing of SP 1. P.A.: In case of PID control, if Auto-tuning is desired whilst the ramp function is active, this will not be carried out until the tuning cycle has been completed. It is therefore recommended that Auto-tuning be started avoiding activating the ramp function and, once the tuning is finished, deactivate Auto-tuning ( Auto = ), program the desired ramp and, if it automatic tuning is desired, enable the Self-tuning function. 5 - PROGRAMMABLE PARAMETERS TABLE Here following are described all the parameters available on the instrument.
